We have tried all the signature restaurants and we liked Yachtsman's and Naracoossee's the best. Both were outstanding! Flying Fish is another favorite.
I must agree about Artist's Point not being as good as it used to be. We ate there Dec. 08 and we were very disappointed. The food and service are good but not nearly as good as the other signatures. Unfortunately, we don't think Brown Derby has been worth two dining credits for quite some time , and it used to be one of our favorites.
It's been a while since we've been to California Grill (2000), and we have it on the list for this year. From most of the current reviews you see here, I'm sure it will still be as great as it was then.
